Question

divide the reciprocal of 2/5 multiply by -10/3 by 1/2-1/3

Answer 1

well,
here the reciprocal of 2/5 is 5/2 = 2.5
so,
2.5 x -10/3 = -25/3
now,
1/2 - 1/3 = $\frac{3-2}{3X2}$
             = 1/6
now again,
-25/3 x 1/6 = -25/18

Answer 2

2/5×-10/3=-4/3
r.p of-4/3 is -3/4
then,1/2_-1/3=3-2/6=-1/6
-3/4÷-1/6=-3/4×-6=18/4
quotient=4
